Surface Systems, Inc.Jon Tarleton
&Bob Dreisewerd
RWIS and MDSS
• Larger network of RWIS increases MDSS effectiveness
• RWIS – MDSS Training Similarities– Computer Technology– RWIS not complete tool?
SSI RWIS Advancements
• Newer RWIS Platform– Very Expandable (Traffic,
Homeland Security)– More reliable– Easier to maintain– Device Control capabilities
Pavement Sensor Options
Thermo SCAN –Pavement Temperature Only
GroundHog – Inpavement Wireless Traffic Sensor
FP 2000 – SSI making improvements to the sensors reporting capabilities.
SSI Forecast Services Overview
Use of improved weather modeling (utilization of higher resolution models and ensemble forecasts) as the basis for all forecast products.
Use of experienced meteorologists to correct model forecast grids, esp. during the short term.
Proven pavement forecast modeling experience.
An accurate forecast is the foundation of a successful MDSS
SSI’s current version of MDSSStorm Logic
Partnership between SSI and Asset Insight Technologies (AIT) Test viability Get something to market which is easy to use and understand. 2nd full winter with 3x number of customers from 1st year.
AIT provided Treatment Strategy Matrix based on modified FHWA rules of practice.
The AIT maintenance treatment strategy is appended to the SSI SCAN*Cast recommending pre-storm, during storm, and a post-storm treatment strategy for particular site based on “best practices”
Strategy is modified as forecast is updated or changes
Storm Logic forecast considerations
Pre-stormPrecipitation type and intensity (rain or no rain)Pavement temperatureWind speed
During stormPrecipitation type and intensityPavement temperature and trends
Post-stormWind speedPavement temperature until dry pavement
Guidance on how to best treat roadway to optimize safety and costs (material/labor)
Training tool for agencies just getting started in anti-icing programs or for new supervisors
User friendly approach – easy to understand
Benefits of Storm Logic
Based on current customer feedback:1. Customization of treatment
recommendations based on individual agencies.
2. Enhanced road condition and treatment recommendations to provide more specific recommendation timing during the next 24 hours – incorporate modules from MDSS prototype.
